Our present invention relates to tie'plates for special purposes such asswitches, turn-outs and guard rails. The present applicationisa'division of our co-pending application Serial No.

In laying a track without switches or other I constructions the railswhich intersect the tie plates supporting the rails, are very slightlyinclined or canted so as to tilt the rails very slightly toward thecenter of the track. As these tie plates are all alike they may berolled for use in large quantities. However, at switches or turnouts orother constructions in which one rail intersects or crosses another andin guard rails a number of special tie plates must be employed tosupport each of the rails involved in a position that changes for eachtie. This requires the making of a number of special plates instead of Irolling a standard plate as can be done for a track section 'having noswitches or similar constructions. a

I-Ieretofore these special plates have commonly been made with uncantedor horizontal surfaces and it has been necessary to provide a number ofspecially constructed or machined plates of varying inclination orcanting between the canted plates and the uncanted plates so as to avoida sharp change in position of the rails.

An object of our present invention is to provide a plate which may be ofeither canted or unmachined or machined and welded to form a number ofspecial plates and in this way enable various'special shapes to beformed from a single rolled plate section.

The invention is illustrated in the accompanying drawings, in which-Fig. 1 is a plan view and Fig. 2 an end elevation of a special rolledplate which may be canted or uncanted and from which a number of specialplates may be formed.

Figs. 3 and 4 are views of special shapes formed from the plate of Fig.1.

Figs. 5, 6 and '7 are edge views of the plate of Figs. 1 and 2 showingthe difierent arrangement of flat and canted plates. 7

Figs. 8 and '9 are side views of other special plates formed from theplate shown in Figs. 1, 2 and 5. V

Fig. 10 is a similar view of a canted plate formed from the plate shownin Figs. 6 and '7.

Fig. 11 is a plan view of another type of plate formed from the platesof Figs. 1 and 2 The rolled plate'shown in Fig. 1 and which may becanted in either direction or uncanted as outer face of the wider rib soas to provide ribs inner edge of the wider rib I 2 has been mashown inFigs. 5, Sand 7 has a base plate l provided with a narrow rib II and awider rib I2, these ribs running crosswise of the plate at suitablyspaced distances and being undercut at I3 and [4 respectively to formthe bolt head receiving recesses. The plate ID with the ribs II and I2may be rolled in the usual manner and cut to individual plates, andplates of various types may be formed by machining the inner or ofdiiierent spacings as required. The outer end of the plate is thensheared to form a symmetricalplate.

' The plate shown in Fig. 3 is one in which the chined to form a rib I5of the standard width but spaced a greatervdistance from the rib ll thanthe inner edge of the original rib 1 12. In the event that the spacingbetween the ribs may be intermediate that of the inner edge of theoriginal rib I2 and the edge of the rib. l5, the rib l2 may be machinedfrom either or both edges so as to give any desired rib spacing.

In some cases it is necessary to have the ribs slant from a trueperpendicular relation to the side edges in order to fit crossingtracks. In

, these cases the edges of the plate Ill may be sheared as indicated bythe broken lines it and I! and then the edge of the rib I2 may bemachined to provide the correct spacing. The plate I!) may also be usedin forming the plate l8 shown in Fig. 8. This may be accomplished bycutting a groove I9 in the wide rib [2 to form two ribs 20 and 2|, thenshearing the plate within the rib l I and welding it to a plate 22having an undercut 23 to receive the flange of a rail 24. The ribs 20and 2| serve to secure and hold a wedge 25 serving to wedge a brace 26which is held downwardly onto the plate I8 by means of a bolt 21 securedin a rib 28 formed on the plate 22 before welding,

It will be understood that a canted plate may be used in a similarmanner to form a plate similar to the construction of Fig. 8 buthaving acanting support for the rail 24.

In case a pair of rails, such as a main rail and a switch rail or guardrail, are to be supported in closely spaced relation, a plate such asthat shown in Fig. 9 may be required. In this case a plate I0 may besheared within the narrow rib H and then welded to a second ribbed plateoutside the narrow rib as, for example, at 29 in Fig. 9. One of thewider ribs may then be grooved V as at 30 to provide a pair of closelyspaced ribs 3| and 32 and the other wider rib may be similarly asgrooved or may be machined to form a single narrower rib such as the rib33.

It will be understood that in this case also canted plates of theconstruction shown in Figs. 6 and 7 may be employed so as to cant therail supporting surfaces of the special plate in either direction asrequired. I

A canted plate formed from the rolled plates of Figs. 6 and '7 is shownin Fig. 10 in which the plate of Fig. 6 is sheared on a line 34 andanother similar plate is sheared on the line 35' and then the two platesare welded ontheweld=36 of Fig. 10.

Thereafter the wider rib. l2? may? be planed away as indicated by thedotted. lines of Fig. 10 to provide the narrow outer rib 38. Or, ifnecessary, two plates suitably sheared may be-welded as at 36 and 31 toa broad rib 38.;as'indicated in Fig. 10, provided it is'necessary toform a plate having a rail supporting surface wider or, narrower thanthat between the ribs l l and. In

constructing a plate suchas that of; Fig. 10, the

ribs 38 and 39 maybe planed toform two track supporting surfaces 40 and4|. that diverge or lie at an angle to each other.

By using a canted plate-in the above manner it will be possible to formplates in which the cant of the rails may be carried directly throughthe switch orturn-out or other construction, and thereby avoid thenecessity of transition plates of graded cant.

The above are merely illustrative of the various ways in which specialplates may be made from a rolled section by providing on such sectionspaced ribs one at least of which is of suflicient width to permitmachining'so asto enable the distance between the ribs to be modified,or double ribs to be formed, or various combinations of plates to bemade and-the rib spacings thereof adjusted.

Various modifications may be made by those skilled in the art withoutdeparting from the invention as defined in the following claims.

What we claim is:

1. A method of forming rail supporting tie plates which comprisesrolling a plate with spaced transverse ribs, one of said ribs beingwider than the other, machining said wider rib from a side edge to thewidthof the' narrower rib and to a spaced distance-therefromand shapingsaid plate to a desired dimension.

2; A method of making rail supporting tie plates of selected dimensionswhich comprises rolling a plate with spaced transverse ribs, one of saidribs being. materially wider than the other, shearingtheside-edges ofsaid plate to an oblique angle to said ribsand machining said wider ribto provide a selected'distance between said ribs.

3. A method of forming rail supporting tie plateswhich comprises rollinga plate with spaced transverse ribs, one of said ribs being wider thanthe other, shearing said plate within one of said ribs and welding itend-to-end to a similar unsheared plate.

4. A method of forming rail supporting tie plateswhich comprises rollinga plate with spaced transverse ribs, one of 'saidribs being-wider thanthe other, shearing said plate withinone of said ribs. and welding itend+to'-end to a similar unsheared plateand machining said wider ribs toa selected rib width and spacing.

5. A method of forming rail supporting tie plateswhich comprises rollinga plate with spaced transverse ribs, one of said ribs beingwider thanthe other, shearing said plate within one of said ribs and welding it.end to end to a similar unsheared plate, and machining said widerplates to a selected rib width and spacing and having the side faces ofthe central rib extending in a hori-- zontal angle to form divergingtrack supporting surfaces.
